<p>now im taking ap us history and ap chemistry,actually i understand the material...but i really need more practice.should i buy books like Barrons,PR for practice?or try to buy the released exams???(is the answer key included?)</p>
<p>I would recommend buying prep books like Barrons, PR, etc. I find them to be VERY helpful. Highly recommended. :) Good Luck!</p>
<p>Practice exams are good, but they are kind of a rip off in terms of experience for the dollar. </p>
<p>I recommend Barron's (in general, though for APUSH, definitely get Amsco</a>)</p>
<p>It's a great review, and the MCs are actually "good" -- gets you thinking about it .</p>
<p>They also have actual DBQs in there, as well as guides on writing the essays. </p>
<p>They also have lists of "key terms" as well as essay questions. </p>
<p>I've done an entire review on this book, check it out here: AP</a> SAT Central: AMSCO's "United States History - Preparing for the Advanced Placement Examination"</p>
<p>^^i like amsco,but the answer key is not included along the book??????/</p>
